To Ir/ZZ tub/077e it may concern: I

Be it known that I, BERT RIvKrN, a citizen of the United States-residing at New York, in thecounty of New York and State of New 5 York, have invented certain newnand useful Improvements in Street andStation Indicators for Tramway or other Cars, ofwhich thefolf.

lowing is aspeciication, suchas will enable thoseskilledin the art to which it appertains to make and use the same.

The object of this invention is to provide an improved street and station indicator for tramway and other cars which is Vdesigned to be placed in a car and by means of which the names of thevario'us streets on the-line of a tramway or street-car track or the stations on a railway may be displayed in such'a mane ner as to be-conveniently. read bythe occu; pants of a car; and with this andotherobjects in view the invention consists in an indicator of vthe class described constructed as hereinafterdescribed and-claimed. s v l x The invention is fully disclosed in the fol-l lowing specication, of which the accompany-4 2 5 ingdrawingsform apart, in which the separate parts of my improvement are designated by suitable ,referencecharacters in each of the views, and in which* f dicator; Fig. 2, a,similar'vviewwithone side of the casing removedand part of the construction shown-in section; Fig.' 3, a sectional plan view, and Fig. 4 a vertical section on the line 4 4: of Fig.' 1 and on an enlargedscale.`

'v In l, the ractice of kmy inventionl provide an oblong ox or case a, the sides a2 of whichA are provided in Itheir inner surfaceslv with a groove (t3, theendsof which aresegmental 1n form, and the ends of the boXvor casca are also segmental in form, and the grooves a3 form tracks or ways, as hereinafter described.

Mounted in the boX or case a and connected with the side walls a2 thereoflby means of transverse members b, which are rigidly secured thereto by screws lor other devices Z22, is a rigid frame comprising a central member b3, with which the members b are rigidly connected or in connection with which said members are integrally formed, and connected with the transverse member b, which formsa 'senti no. 162,893. @Nt modem d l-partof the saidframe, and at each side-ofthe lbox or case is an endless trackor way. 2f, and `-these tracks or waysb4 are ofthe same gen-- eral form as the grooves a3 andy correspond, therewith., The tracksorL ways 54 form apart 5 5 lof the central frame, and the part t? of said lframe is provided with end extensions '65, 1in which are mounted sprocket-wheels c and 02 and the sprocket-wheel.l c is mounted on a shaft; :03,: which passes through one side of the boX or case and is'providedwith a gear-wheel cl.

' ,Monnted-onthesprocketfwheels c and A.c zis; 'an endless chain d, .thelinks ,d2 of which are ,provided with rigid sidearms dns, with which, f arerigidly connected card-framese, arranged. at right angles to the endlesschain" d, and the, frames e are previded with membersre?, whichI engage the endless tracks .or ways btandare provided lwith grooves e3; for 4this,purpose Each of the frames e consists of' end member "7a.

j', the ends of which rest in thetg voyes in,Y 75' the sides a3 of the main box or case @,and each,A 1 of these rods is provided ,with a ca rd f2, and t Y the vbottom portion of Lthe, sidesf' ofthe box-l Figure 1 is aside'viewof my improvedin- L or case a are provided centrallywith venti- ,"-v

ofthe rods f are free to move, andthe bot-3; l tom portion ofJsaid boX or case ,is v'provided with a' similar transverse opening a5, throughv whichthe cards f2 are free to pass.

Passing transversely through the 4boxer 8'5"` case t and through the rigid framememberA b3 is a shaft g, one end of which is yprovidedvwith a gear-wheel g2, which operates -in c on-L nection with the wheel of, and, thelothergend, of which is provided with two ratchet-Wheels 90 g3 and g4, the teeth of which ,project in oppo sitedirections, and beneath the. wheels gand-y f g4 a lever /t is pivotedto the side of Ithe box. or case a, as shown at i?, and this lever is provided at its upper end with a transverse head l95. 71,3, in which are pivoted two spring-operated I dogs and h5, which operate, respectively, in connection with the ratchet-Wheels g3 and gf, and connected with' the lower or free end of the ,lever /t and secured to the box or Aoase a,

at the opposite sides thereof are springs /LG and if, which serve to hold said lever normally in a rvertical position, as shown in Fig. 1.

Mounted above the box or case a transversely thereof and supported thereon is a shaft t', the opposite ends of which are provided each with a pulley-wheel 2, with each of which is connected a cord 3, and these cords 3 are connected with vertically-movable hangers j, which pass through keepers f2, connected with the opposite sides of the box ,or case a. The lower end of each of the verticallymovable hangers t" is provided with an inwardly-directed hook member, which members pass into the vertically-arranged slots or openings in the sides of the box or case a, and the ends f of the rods a* are adapted to rest on the hook members ,7'3 of the verticallymovable hangers j' and to be raised thereby. One or both of the hangers j are provided with a collar'lc, between which and the upper keeper or keepers f2 is placed a spiral spring 7a2,

and one of the cords 3 passes loosely over the corresponding wheel 2 and downwardly between two guide-pulleys 7c3, secured to the bottom portion of one side of the box or case a, and said cord 3 is connected with an operating-cord m, which passes loosely through the lower end of the lever L, as shown at m2, and is supported by two pulleys m3, secured to the bottom'of -the box or rease a at or near the opposite ends thereof, and the cord m extends to both ends of the car in which said box or ease is placed and may be operated from either end of said car. The cord m is also provided on the opposite sides of the lever 7L and at a predetermined distance therefrom with stops a and a2, and the cord 3, which passes between the guide-pulleys 7e3, is provided with a spring member a3, which is placed therein between the guide-pulleys las and the pulley 2, over which said cord passes.

If my improved indicator is used' on a streetcar trackor tramway, the cards f2 will bear the names of `the various cross-streets along the line of said track or tramway arranged in regular order, and at each pull of the cord m in the direction of the arrow x (shown in Figs. 1 and 3) the chain ci will be moved through one space in the direction of the arrows 2, (shown in Fig. 2,) and at each pull of the cord m inthe direction of the arrow y in Figs. 1 and 3 the chain d will be moved one step inthe direction of the arrows y2 in Fig. 2.

In Figs. 1, 2, and i of the drawings one of the rodsf,'with`itscardfz, is in its lowermost position, and the name on the card f2 may be read by anybody in the car. At the beginning of the pull on the cord m in the direction of the arrow the said rod f and its corresponding card-f2 are raised into their normal position within the box or case a by means of the hangers j', and this occurs before the stop a strikes the lower end of the lever la, at which time the ends of the said rod are in position to enter the grooves a3, and as the pull on the cord m in the direction of the arrow :i: is continued the dog engages the ratchetwheel git and moves it, thereby turning the shaft g and the gear-wheel g2, and by this operation the shaft c3 is turned through one step and the said rod f moves forward one step. At this time the cord m is released, and the hangers j drop into the position shown in Fig. 4, and another rod f drops into the position shown in Figs. 1,2, and 4, and another card f2 is exposed. It will be understood that this operation is repeated as the ear proceeds on its way, and when the car reaches the end of the line and starts on the return trip the cord m must be operated from the opposite end of the car, and pulls thereon in the direction of the arrows 1/ in Figs. 1 and 3 will bring the stop 11,2 on said cord into operation, and the result will be the same as hereinbefore described except that the movement of the shaft c3 and of the chain (lis reversed, and the operation of my improved indicator would be the same on an ordinary railway except that the names of the stations would take the place on the cards f2 of the names of crossstreets.

My improved indicator is exceedingly simple in construction and operation and perfectly adapted to accomplish the result for which it is intended and may be employed on street-cars or on ordinary railways and whenever devices of this kind are required.

My invention is not limited to the exact form, construction, and arrangement of the various parts thereof as herein shown and described, as many changes therein and modifications thereofA may be made without departing from the spirit of my invention or sacrificing its advantages, and I reserve the right to make all such alterations therein as fairly come within the scope of the invention.
